HIGHPOINT® INVISARIDGE™ EXHAUST VENT
INSTALLATION INSTRUCTIONS
Remove ridge cap shingles from the entire
length of the ridge. Note: Delete Step 1 for new
construction.
Nail each additional section in the same manner
until entire ridge is covered. A chalk line may be
utilized to ensure vent alignment. Cut last piece
to length and install with original uncut end to
the outside.
Install new ridge cap in normal manner, using
2-1/2” roong nails, for 3/4” deck penetration or
penetration through the deck, whichever is less.
Nailing the ridge caps through the vent along
the nailing line will secure the vent. Shingles
may need to be trimmed.
Ridge-to-ridge application requires a mitre-cut
to maintain continuous ridge line appearance.
Ridge-to-roof application requires a mitre-cut
to maintain continuous ridge line appearance.
Cut along chalk lines. Remove roof sheathing.
Note: Slot should not be cut any closer than
within twelve (12) inches of gable end, hip
intersecting ridge.
For appearance (to blend with the roof line), it is
recommended that the HighPoint® vent be
installed the entire length of the ridge. Position
the rst piece at one end of the ridge. Using
2-1/2” nails, for 3/4” deck penetration or
penetration through the deck, which ever is less,
anchor vent through preformed nail holes.

the pole into the attic space - but do not remove
more than 2-1/4” of roof sheathing material from
either side of the ridge. Refer to ridgepole diagram.
